Gigabyte 1060 6GB sometime 0sol/s

Hello everyone,
I have a rig of x6 Gigabyte 1060 6GB
sometime it doesn’t work and show 0sol/s
Window 10
Ram 4Gb
Motherboard B85
There is no power or internet connection issue
anyone has the same problem?

EWBF crashed!
too much OC?
try stock settings

Help me,
anyone has the same problem?

Clock setting ? any GPU or MEM mod done? , driver you are useing? and of course what have you tried so far to fix the issue

as for the miner failing top post can you please check the RAM usage when mining as 4 GB of RAM seems to low in case a 6GB Vram GPUs used
